Medical colleges and universities needs original human bodies for for Anatomy Dissection classes , In my first year in medical college when i was a fresher , i used to regret because the Cadavers(Dead bodies preserved in formalin) are mainly people suffering from extreme poverty , homelessness or they may be unclaimed bodies and they didn't got proper ceremonial burial after their death. but at the same time it was in my mind that Dissecting dead human bodies is very necessary for medical education (especially surgical branches)
Today i realized the importance of Quranic silence on this matter.
